Until ackbarr releases 2.02 version (hopefully very soon ), anyone uses the newsletter module on a production site is recommended to update.
1) fixed page navigation to show all newsletters in the archives 2) hided newsletter admin email for security measures (preventing email harvesting and spamming) 3) removed search function in the archive template file (for now, as it is not working)
The whole package and patch could be downloaded from http://xoops-tips.com
